Does anyone know if gptfdisk checks for optimal alignment or if I would need to use parted after?
I found an option in gptfdisk to set alignment but it expects me to set the alignment as where parted just works.
Parted is ancient compared to gptfdisk. Can someone explain this?

I read this on the arch wiki but i'm still unclear on this:
Does anyone know if gdisk will be able to align correctly for 512e disks as well as advanced format disks?
I have a couple old laptops with 512e disks and I feel like I might need to know this.

As far as I know gdisk is a drop in replacement (enhancement) to the legacy fdisk that has been around for ages. Its major change seems to be that it is more specialized for gpt partitioning and for the newer larger block size as noted above.

Personally, I've never used such commands — my Linux distros have always come with a GUI, so why not use it? If you use gparted, it has this advice partition alignment

Each tool has its place. I use gparted, fdisk, and gdisk as appropriate. Gparted seems the best so far in the gui world.

I like parted for automation of partitioning within a shell script.

It seems that everyone has a different preference or oppinion in this topic.
I read a few pages written by Rod Smith: www.rodsbooks.com/gdisk
Some parts helped explain his intentions in creating his program and how it works.
I believe that it assumes for 4k native sectors.

I won't analyze gptfdisk but I believe that was the intention in it's creation.

I'm trying to create a scripted installation of Arch, as I am a "Newbie" and I'm running EndeavourOS.
sgdisk seemed to be the best option until I had to try to understand how alignment and 512e disks are handled.
